be specifically separated from our T. Glottis, is satisfactorily shown by Brchm 

 (1. c. p. 894). 



Among the Greek Plovers Count v. Mlihle would distin- 

 guish a Numenius syngenicos. (Beitv. p. 111.) 



It is a doubtful circumstance, as respects the independence of this species, 

 that it is founded upon a single specimen, and that the habit, though 

 remarkably different from that of the other three European species, neverthe- 

 less presents " no strikingly characteristic feature." 



Size, figure, and feet of N. plueopus, bill weaker and shorter, outline of head 

 precisely as in N. arquatu, sides without black shaft-spots ; black shaft-spots 

 of the under part of the body not as in N. tenuirostris, cordate, but lanceo- 

 late ; shafts of the first three large wing feathers wliite ; lateral feathering of 

 the under mandible not reaching above the upper. 



Blyth (Ann. xii, p. 74) is inclined to place Glareola among the Capri- 

 mulgrnae. 



NATATORES. 



LONGIPENNES. Gould has made known four species of Sea Swallows from 

 Australia : Sterna vclox, Hi/Jroclielidon Jlwviatilis, Tfialassem Torresii, and 

 Sternula Nereis. (Ann. Nat. Hist, xii, p. 67.) .From Peru, by Tschudi : 

 Sterna acutirosfris, and exilis, as also Larus modestits. (Archiv. p. 389.) 



TUBINARES. The European Eauna has received an 

 accession in a newly instituted species, Procellaria (Tha- 

 Jassidroma) melitensis. (Ann. Nat. Hist, xii, p. 42.2.) 



This name appears to have been given by Schembri, of whom Drummond 

 says, that he discovered the P. melitensis at Malta, where it breeds in great 

 numbers on the rock of Filfola, whilst T. pelagica is not known there. 

 Drummond thinks that it may be peculiar to the Mediterranean, and remarks 

 that in his homeward voyage he observed it in multitudes, but that after 

 passing the Straits of Gibraltar it was replaced by T. pelagica. The two 

 species, as Drummoud says, are readily distinguished ; P. melitensis is rather 

 the smaller, and has the lower half of the tail feathers, as well as the rump, 

 white. Malherbe mentions the same rock at Malta, but assigns P. pelagica 

 to that locality, of which species he also says that it comes from Sicily. 

 Whether or no he examined specimens himself cannot be determined from 

 the account he gives.
